Spain and Portugal Blackout: Can Renewables Save the Day?

Spain and Portugal are facing a massive blackout, with power restoration posing a significant challenge. Their grids have limited external connections, but both countries boast abundant renewable energy sources, particularly hydropower and wind power. Hydro plants require minimal external power to start, and wind power can provide black start capabilities, though it's unclear if local wind turbines are equipped for this and if weather conditions will cooperate. While solar isn't ideal for black starting, its DC nature helps stabilize grid frequency. However, a lack of large-scale battery storage presents a major hurdle to restoring power. Restoration could take several days, depending on grid operators' ability to effectively leverage existing resources.
